, or from amazon (proud amazon prime member here, free 2 day shipping
Now I also did the iTunes thing for TV shows for a while, but have since gotten out of that as well do to the incredibly erratic quality (usually quite poor) of the video. Meaning I could watch one episode of Battlestar Galactica and the quality is acceptable, then watch the next episode and its almost unwatchable. This inconsistency is frustrating at best.
